1. High Alumina Brick Description

High alumina bricks are mainly made of clinker of bauxite and other materials, mixed at high temperature, formed, dried, and sintered. The Al2O3 content of high alumina bricks varies according to different ratios. The general content is stable at 48%-80%, the maximum alumina content can reach 90%, and the refractory temperature can reach 1770℃.
